| Outline of Final Research Achievements |
The purpose of this study was to clarify what effects on muscle activity and neural excitability would occur by applying electrical stimulation to muscles or sensory nerves during normal human walking. The external stimuli given during walking in healthy subjects caused changes in muscle activation levels, common drive to motoneurons, and excitability of the corticospinal tract to the target muscle.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の結果から、ヒトの二足歩行時に与えた非侵襲的な電気刺激によって適応が生じ、刺激をオフにした後にも筋活動などに変化が短期間みられたことから、刺激方法を工夫することで回復をより促しやすい歩行リハビリテーションへと発展することが期待される。また、体重免荷した歩行では免荷による効果が筋によって異なることから、リハビリテーションにおいて筋ごとに注意が必要となることが示された。
